Power Measurement Subsystem
This subsystem programs the power measurement capability of the power source. Two
measurement commands are available: MEASure and FETCh. MEASure triggers the acquisition
of new measurement data before returning a reading. FETCh returns a reading computed from
previously acquired data.
Individual outputs of a three-phase source are specified by the setting of INSTrument:NSELect.
